De nombreuses approches ont été élaborées pour extraire des connaissances à partir des données. On distingue traditionnellement l’analyse descriptive et l’analyse prédictive. Nous nous focalisons dans cette thèse sur l’analyse descriptive des données et plus particulièrement sur l’Analyse de Concepts Formels (ACF), qui permet de construire des clusters recouvrants (appelés concepts formels) dont la signification est explicite. Il existe une relation d’ordre partiel entre les concepts formels résultant de l’ACF, qui sont organisés en une structure mathématique appelée treillis de Galois. Malgré ses nombreux avantages, l’ACF est peu accessible à des utilisateurs non experts de l’analyse de données. En effet, malgré les représentations graphiq...
